CAN.

Specification of Letters Patent.

Patented Oct. 114i, 1919.

To all whom it may concern:

Be it known that we, BEN K. FORD, a citizen of the United States, residing in Oak Park, in the county of Cook and State of Illinois, and ERNEST M. HALLBAUER, a citivzen of the United States, residin at Maywood, in the county of Cook an State. of Illinois, have invented a new and useful Improvement in Cans, of which the following is a specification.

This invention relates to improvements in cans.

One object of the invention is to provide a can or receptacle which may be easily,

y quickly and securely sealed at the place where'filled and so sealed that the can cannot be opened before reaching the user without leaving visual evidence thereof.

Another object ofthe invention is to so I construct the can top and the seam by which the closure is secured in position that provision is made for the reception of a friction slip fitting cap to protect the closure in transit, tlie closure being of such material that it may be easily severed by the user.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described or claimed. In the drawing forming a part of this specification Figure 1 is a perspective view of a portion of a can showing one form of our improvements in connection therewith. Fig. 2 is asectional view showing the top portion of a can embodying our improvements, and Fig. 3 is a similar view but with closure is finally secure the cap removed and showing in dotted position the seam-formin flange before the LI in place.

In said drawing, the body of the can is v'designated by the reference 10, said body being shown as made of paper although 1t may be of any other suitable construction.` The can is provided with a sheet metal top 11 ksecured to the body by a crimped seam 12,

said top having a countersunk portion 13 surrounding an opening 14. rIhe top 11 has `an upwardly extended Bange 15 surrounding and defining ithe opening, an inwardly extending bead 16 formed by doubling the metal ,upon itself as shown in Figs.-2 and 3, and a flange 17 which, before the closure 18 1s applied, occupies the position shown in dotted lines at 19. The closure 18, which may be of paper or any other, relatively -easily severable material, is placed on the shelf or ledge formed by the bead 16 after the can has been filled and 'then the ange 17, p

leaving visual evidence thereof, although the user may readily obtain access to the cans contents by severing they closure 18 with a knife 0r other suitable instrument.

In turning` the flange 17 down upon the closure, an outwardlyextending bead 20 is formed which serves as a friction wall for the flange 21 on the cap or cover 22, lthe flange 21 being slightly curled inwardly at its lower edge so that as it passes over the bead 20 it will snap into position and be firmly held. The top 11 is countersunk to such an extent that when the ca 22 is in position the top of the latter wil lbe substantially flush with the upper edge of the can 'body whereby the cans may be easily stacked for shipping purposes.

Although we have herein shown and descrilbed what we now consider the preferred embodiment of our improvements, yet it will be understood that various changes and modifications may be made without departving from the spirit of the invention, and all such changes and modifications are contemplated as come within the scope of the claim appended hereto.

We claim:

A can formed with an aperture, said aperture being surrounded by an outstanding flange, said flange being bent inward and thence outward to form a seat and being thence bent upward to form an external peripheral shoulder for holding a friction top, and thence 'bent inward to form a securing flange; a closure on said sea-t held beneath said securing flange; and a friction top having a depending friction flange adapted to engage around' and under said external peripheral shoulder.
